What I said instead is pretty straightforward. I made 2 main points:
1. Beliefs inform actions and since atheism is not a belief but a DISbelief of a specific thing, it does not inform actions.
So what motivates all the anti-religious rhetoric from so many atheists? (Illustrated very eloquently in this thread.) Why are so many atheists so
hostile towards religion and towards religious believers? Why all the knee-jerk dismissals? Why all the posturing as if atheists are the paragons of logic and reason, in a position to talk down to everyone else?
Something is seemingly going on here, something is informing those actions, that goes far beyond mere lack of theistic belief.
One would think that if atheists have IQs above room temperature, they would recognize the importance of the metaphysical, epistemological, psychological and existential issues that religion addresses. And if (as they so loudly insist) they don't have any preexisting beliefs about these matters, one would expect an attitude of openness and curiosity about the possibility of learning something important and new.
2. a sense of morality / ethics is inherent to the human condition and does not need to be "given" to us.
I agree that humans have social instincts. These instincts put all of us on the same page so to speak. We identify with our social groups (families, bands, tribes, nations...). We have a sense of reciprocity, the golden-rule thing, a sense of fairness. We have empathy, an awareness of what we take other people's inner states to be and (usually) a tendency to share something of their affective states ourselves ('emotional contagion' it's called in the literature).
Human societies construct more formal and codified moral principles atop that scaffolding. And just empirically, we discover that not all of those moralities are the same. So what happens if two people, or two societies, disagree about some fundamental ethical belief? Is there any underlying truth to the matter? Is there anything besides our own traditions and our own feelings, that informs our moral judgments? Is there any objective truth to the judgment that something that other people are doing is wrong and that they should instead behave like us? If so,
what grounds it?
We are back at the familiar Is/Ought problem. We can construct all the evolutionary ethics we like, we can poke into neuroscience perhaps, to explain why people have the ethical intuitions that they do. But the question still remains, if both our moral intuitions and their moral intuitions can be explained in the same way, what determines that our intuitions are right and their's wrong?
As a secondary point, I said that even if a morality is given to us, we would have to necessarily use some other source of ethics in order to make a value judgement about that "given morality", to recognize it as "good" or "bad".
Yes, I agree with that. It's Plato's old
Euthyphro problem. Does God command x because it is good? Or is x good because God commands it? So arguably religious ethics are in the same position as evolutionary ethics up above. I think that many theologians would address this problem by how they conceive of God. God is supposed to be the essence of Good or something like that. I'm not persuaded though and think that the problem still stands.
